Bayesian networks of the variables that were found to be associated with the subtype of the HIV-1 strain in the univariate analysis. The variables gender, risk group and continent of origin were grouped as described previously. Black arcs indicate variables directly associated with the Subtypes/CRFs variable. Grey arcs indicate indirect association with Subtypes/CRFs. Dotted arcs indicate associations with low bootstrap support (<70%), while full arcs indicate associations confirmed by a high bootstrap support (>70%). Country of sampling included 20 countries: Austria, Belgium, Cyprus, Denmark, Finland, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovenia, Spain, Sweden, Serbia, Czech Republic, Slovakia and Israel. Country of origin included: Netherland Antilles, Angola, Argentina, Austria, Belgium, Burkina Faso, Burundi, Benin, Brasil, Democratic Republic of Congo, Congo, Switzerland, Cote D’Ivoire, Chile, Cameroon, China, Colombia, Cuba, Cape Verde, Cyprus, Czech Republic, Germany, Djibouti, Denmark, Dominican Republic, Algeria, Equator, Estonia, Egypt, Eritrea, Spain, Ethiopia, Finland, France, United Kingdom, Georgia, Ghana, Gambia, Guinea, Equatorial Guinea, Greece, Guinea-Bissau, Croatia, Ireland, Israel, India, Iraq, Iran, Iceland, Italy, Kenya, South Korea, Liberia, Luxembourg, Latvia, Libyan Arab Jamahiriya, Morocco, Myanmar, Mauritania, Mexico, Malaysia, Mozambique, Niger, Nigeria, Netherland, Norway, New Zealand, Oman, Peru, Pakistan, Poland, Portugal, Romania, Russia, Rwanda, Sudan, Sweden, Singapore, Slovenia, Slovakia, Sierra Leone, Senegal, Somalia, Suriname, Sao Tome and Principe, Syrian Arab Republic, Togo, Thailand, Tunisia, Tonga, Turkey, Tanzania, Ukraine, Uganda, USA, Uruguay, Venezuela, Serbia, Zambia, Zimbabwe and South Africa. However, only to keep the number of instances in the variable country of origin similar to the number of instance in the variable country of sampling; only instances of Austria, Belgium, Cameroon, CS (Serbia), Czech Republic, Germany, Denmark, Spain, Ethiopia, Finland, Greece, Italy, Nigeria, The Netherlands, Norway, Poland, Portugal, Sweden, Slovenia, Thailand and Yugoslavia were left ungrouped; while all other instances of country of origin with smaller sample size were group together.
